To all whom it may concern:

Be it known that I, HENRY W. JV/inn, a citizen of the United States,residing at Henshaw, in the county of Union, State of Kentucky, haveinvented certain new and useful Improvements in Disk-Roller Sharpeners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to a machine for sharpening disks and moreparticularly adapted for sharpening cultivator and harrow disks.

'I he primary object of the invention is the provision of a machine forsharpening disks and having superposed cooperative rollers between theextremities of which is interposed the edge of a disk mounted upon anadjustable su port so that the metal of the disk will be ro led by theaction of the rollers to present a sharpened peripheral edge on the disr.

Another object of the invention is the provision of a machine forsharpening disks such as cultivator or harrow disks and includescooperative presser rollers adapted to act upon the 1peripheral. edge ofthe disk whereby the meta of the disk at its peripheral edge will berolled or thinned out thereby sharpening the edge by the action of theroller and manually operable means for adjusting one of the rollers withres ect to the other where by the said rollers wil be brought in closerelation to each other.

v v ith these and other objects in view, the invention, for example,consists in the construction, combination and arrangement of parts,which will be hereinafter more fully described in detail and asillustrated in the accompanying drawings which disclose the preferredembodiment of the invention, however, changes, variations andmodifications may be made such as come properly within the scope of theclaims hereunto ap ended, without departing from the spirit of theinvention.

In the drawings :Figure 1 is a side view of the invention. Fig. 2 is atop plan view. Fig. 3 is a rear end View. Fig. 4 is a verticallongitudinal sectional view of the machine. Fig. 5 is a transversesectional view on the line 55 of Fig. 1. Fig. 6 is a front end view ofthe machine. Fig. 7 is a perspective view of the front top bearing blockor boxing. Fig. 8 is a perspective view of the disk carrying block.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

In the drawings, the numeral 10 designates a base of any desirable shapeand material and having near the front end thereof an inverted U-shapedguide frame or boxing 11 having lower right angular extensions 12secured by bolt fasteners 13 to the upper face of the base 10 and on theinner face of the opposite side arms of the frame or boxing 11 areguides 14 terminating a distance removed from the cross connecting piece15 of the said frame. Upon the base 10 at its rear end is mounted abearing block 16 having in its upper face centrally thereof a groove 17into which is mounted the reduced extremity 18 of a presser roller 19,the opposite extremity of which is j ournaled in a groove 20 in theupper face of a boxing 21 which latter has oppositely disposed sideextensions 22 for sliding engagement and adapted to lie on oppositesides of the guides 14 of the frame near the front end of the base. Thispresser roller 19 has its front end projecting beyond the box 21 andterminates in a beveled reduced extremity 23. Superimposed upon thehearing block 16 is a block 24 having in opposed faces grooves 25 thelower one of which partially surrounds the reduced extremity 1.8 of thelower presser roller 19 to hold the same in operative position. Mountedupon the block 24 is a bearing block 26, the latter having a groove 27and into which latter and the groove 25 is journaled the reducedextremity 28 of an upper presser roller 29 which has its opposite endnormally resting upon the lower presser roller 19 and mounted in agroove 30 formed in the under face of a sliding block 31 havingextensions 32 engaging opposite sides of the guides 14 so that saidblock can be moved in the frame. To move the sliding block 31 there isprovided a screw threaded stem or member 33 working in a threadedopening 34 in the cross connecting piece 15 of the frame and the lowerend of which stem or member 33 is adapted to engage a countersink 35centrally in the top of the said slidable block while the opposite endof said stem receives a detachable crank handle 36 whereby the stem maybe actuated to limit the upward movement of the upper presser roller 29with respect to the lower presser roller. The front end of the upperpresser roller 29 is beveled as at 37 so as to form a cooperativeworking extremity with the beveled extremity 23 of the lower roller.

Passing through the superimposed bearing blocks at the rear end of thebase 10 are bolt connecting rods 38 whereby the said blocks are securelyheld upon the base. On the reduced extremity 18 of the lower presserroller 19 is secured a driving gear 39 which may receive its motion fromany suitable power and is adapted to actuate or rotate the lower presserroller and which imparts motion from gear 18 to the enmeshing gear 28 tothe upper presser roller.

Upon the base 10 in advance of the beveled extremities of the presserrollers is secured a bracket 40 having spaced upwardly extending cars 41into which is journaled a shaft 42 having a manually operable crank 43at one end thereof and fixed to the said shaft between the ears is anadjustable support including spaced arms 44 united at their oppositeextremities by a cross piece 45 having a central opening 46 whichreceives a threaded advance screw 47 which latter is adapted forrotation and prevented against longitudinal movement in the support bycollars 48 surrounding the screw on opposite sides of the cross piece 45and upon the end of the advance screw 47 is a hand crank 49 whereby thesaid screw may be rotated. Between the arms 44 is a slidable member 50in threaded engagement with the advance screw 47 and which member hasspaced oppositely disposed flanges 51 for engaging opposite edges of thearms 44 and guided thereby during the sliding movement of the member.Projecting upwardly from the member 50 is a stud or pin 52 upon which ismounted the ordinary disk 53 used on plows, cultivator-s and the like,the peripheral edge of which is adapted to be brought into a positionbetween the beveled extremities and 37 which latter will roll or thinout the metal of the disk at its peripheral edge so as to sharpen thesame.

i t is of course understood that during the rotation of the presserrollers while the peripheral edge of the disk 53 is in operativeposition between the beveled extremities of said rollers the said diskwill be caused to rotate on the pin or stud 53 Wher as, the metal of thedisk will be rolled or thinned in a uniform manner while being actedupon by the presser rollers. The crank 43 is actuated when it is desiredto raise or lower the ad justable support so as to change its angularposition. The said crank 43 is fixed to the end of the shaft 42, whichlatter is ournaled in the ears 41 and has fixed thereto the support forthe plow disk so that upon turning the shaft 42 in one direction it willlift the opposite end of the support to the desired angle with respectto the base of the machine.

For maintaining the support in an angular adjusted position there ispivotally connected to the arms depending legs or straps 54 having aplurality of openings 55 for receiving a lockipg pin 56 and said legspass through openings 57 in the base 10.

To accommodate different styles of disks such as are provided withsquared central openings there is provided a squared sleeve or die whichis adapted to be removably fitted onto the pin or stud 52 to supportsaid disk.

What is claimed is 1. In a machine of the class described, a base,superimposed bearing blocks mounted upon the base at the rear endthereof, a frame mounted upon the base a considerable distance removedfrom the bearing blocks and having vertical guides on opposite innerfaces thereof terminating a distance removed from the top of said frame,a removable box engaging the guides and arranged in the lower end of theframe and containing a bearing seat, a vertically slidable bearing blockmounted in said frame above the box, the said slidable bearing blockbeing provided with a bearing seat in register with the hearing seat inthe box, a lower presser roller-horizontally disposed above the base andhaving one end ournaled between a pair of the hearing blocks at the rearend of the base and its forward portion resting in said box, an upperpresser roller having one end journaled in the bearing blocks at therear of the base to permit slightly vertical swinging movement and theother end normally resting upon the lower presser roller and Within thebearing seat of the slidable bearing block, and an adjustable screwmounted in the frame to limit the sliding movement of the said slidablebearing block.

2. The combination with a disk roller sharpener, having a base, of anadjustable support having its lower end pivotally con nected to thebase, legs depending from said support, a locking pin engaging said legsand the base to maintain the same in adjusted position, and a hand crankconnected to the pivoted end of the support to permit raising andlowering of the latter.

In testimony whereof, I my signature, in presence of two witnesses.
